Between 1997 and 2006, we treated 11 patients with tuberculotic spondylitis and 19 with pyogenic spondylitis using a two-staged operation (posterior spinal instrumentation, followed by anterior debridement and fusion). We compared changes in inflammatory reactions, postoperative complications, organisms obtained during anterior debridement, neurological status, bone union, and suppression of the ...

Symptom response to spinal cord untethering, and the impact of duraplasty and scoliosis on retethering, are poorly understood in tethering after myelomeningocele (MMC) repair. In this retrospective study, the authors examined the outcomes of children who developed first-time spinal cord tethering following MMC repair. The response of symptoms to untethering ...

The surgical approach and treatment of thoracolumbar osteoporotic vertebral collapse with neurological deficit have not been documented in detail. Anterior surgery provides good decompression and solid fusion, but the surgery-related risk is relatively higher than that associated with the posterior approach. In posterior surgery, the major problem after posterior correction ...

A balanced sagittal alignment of the spine has been shown to strongly correlate with less pain, less disability, and greater health status scores. To restore proper sagittal balance, one must assess the position of the occiput relative to the sacrum. The assessment of spinal balance preoperatively can be challenging, whereas ...

We evaluated the efficacy of anterior fusion alone compared with combined anterior and posterior fusion for the treatment of degenerative cervical kyphosis. Anterior fusion alone was undertaken in 15 patients (group A) and combined anterior and posterior fusion was carried out in a further 15 (group B). The degree and ...

Prospective radiographic outcome analysis. Radiographic evaluation of the rigidity of monocortical and tricortical purchase in lumbosacral fixation. The lumbosacral junction continues to be a difficult region to obtain a successful spinal arthrodesis and is one of the primary regions for construct failure. In inserting sacral screws, 3 types of purchase ...

Studies suggest that the annual incidence of symptomatic adjacent segment disease is 2-3%. Because biomechanical studies have shown increased stress at levels adjacent to a fusion mass, some surgeons have advocated including the normal level in the fusion construct in patients presenting with noncontiguous cervical spondylosis requiring surgical intervention. Our ...

Anterior cervical decompression and fusion (ACDF) is a widely accepted surgical procedure for the treatment of cervical degenerative disc diseases. This retrospective study was designed to analyze and compare the efficacy and outcomes of anterior cervical fusion using stand-alone polyetheretherketone (PEEK) cages and autogenous iliac crest grafts with the anterior ...

There is a continued role for anterior spinal fusion (ASF) in the treatment of thoracolumbar scoliosis.

Of these 28 patients, 20 patients were included ...

Fusion of the first metatarsophalangeal joint is considered a `gold standard' procedure for arthritis and as a salvage procedure for previous failed surgeries. Recent biomechanical studies have shown that a combination of a plate and screw is the most stable construct. Only a few studies have evaluated this combination and ...
